GAIMC-PT100 GTS300 High-Temperature Sensor for Chimney Applications

Standard PT100 sensors use conventional cable insulation that begins degrading at temperatures above 200°C. At 600°C chimney exhaust temperatures, this insulation quickly breaks down, causing short circuits, sensor failure, and potential safety hazards within days of operation.

The mica core provides excellent electrical insulation at temperatures up to 1000°C, while the stainless steel braiding offers mechanical protection and heat dissipation. This two-layer construction maintains both thermal endurance and cable flexibility, unlike rigid ceramic alternatives.

The extended heat shrink provides additional thermal protection at the transition point between high-temperature and standard temperature zones. It prevents heat damage to termination points and ensures reliable connections to control systems outside the high-heat environment.

Yes, the GAIMC-PT100 GTS300 is suitable for various high-temperature applications including industrial furnaces, engine exhaust monitoring, boiler systems, and any environment requiring reliable temperature sensing up to 600°C with exposure to harsh gases and particulates.

While 3-wire or 4-wire configurations offer better lead resistance compensation, the 2-wire design simplifies installation in high-temperature environments. For chimney applications where cable runs are typically short (1.5m in this case), the lead resistance error is minimal and acceptable for combustion control and safety monitoring purposes.
